drill to fix hidden hitch and yakima big horn incompatibility?
I recently put a class I 1 1/4" Hidden Hitch on my Kia Rondo, and got a 1 1/4" Yakima Big Horn 4 bike rack to use with it.
However, it seems that the hidden hitch has a small "tab" near the back of the receiver, making the receiver deep enough to put the hidden hitch branded drawbar in, but about 3/8" too shallow to put the Big Horn 4 in enough to line up the pin holes. The "tab" is basically just a 1/4" circle of the square receiver tube that was cut out on about 3 sides and punched inward.
So from a load bearing perspective, the "tab" already weakened (obviously not significantly) the receiver since its only attached on roughly 1/3 to 1/4 of the circle. Does anyone see any reason why I can't just drill out the "tab" and turn it into a hole in the receiver, so that the Big Horn 4 can be slid in all the way? I can't imagine it will weaken the hitch much if at all, and putting the bike rack 3/8" further into the receiver will only reduce the leverage on the hitch/frame/suspension, right? I don't understand any technical reason why this "tab" would be there in the first place.
